Are Diesel Engines Better Than Petrol Engines?

diesel mechanic job description

Many people like to compare diesel and petrol engines. And most of the times, people think that petrol engines are far better. Sure, petrol engines are able to operate at higher RPMs, making them faster. But diesel engines have a lot more going for them in other places. A diesel engine vehicle can be surprisingly fun to own. It has a high torque output, is far more fuel efficient, and is a lot more durable as well. A diesel engine’s superior performance is all owed to its unique internal mechanism.

At a glance, diesel engines and petrol engines both operate in the same way. They have a combustion chamber that mixes air and flammable fuel in order to produce energy. This energy then transfers into the engine and brings it to life. However, diesel and petrol engines achieve combustion in different ways. Petrol engines rely on spark plugs for igniting fuel. Diesel engines ignite fuel through extreme air compression.

A diesel engine compresses air in order to increase its temperature. Extreme compression results in the air’s temperature rising to extreme points. And as a result, the high temperatures cause the diesel fuel to ignite. This method of combustion allows for better fuel efficiency. It also makes the engine tougher in a number of ways. The engine is built quite sturdily to withstand the pressure from high air compression. It also doesn’t have any spark plugs in it, reducing the need for frequent maintenance. A diesel engine has a much longer lifespan as compared to petrol engines.

They’re quite tough indeed, but they still need regular maintenance. Repairing a diesel engine can help further increase its lifespan and maintain its fuel efficiency. This is why one should have a reliable diesel engine workshop in mind.
